An SSL certificate chain comprises a sequential arrangement of certificates, including the SSL/TLS Certificate and Certificates from Certificate Authorities (CAs). This chain allows the recipient to authenticate the credibility of the sender and the involved CAs. Within each certificate, there’s data about its issuing authority, serving as a successive connection in the chain. The typical …

Here’s an overview of each format: PEM Format Text-Based Format: PEM (Privacy Enhanced Mail) is a Base64 encoded format used for certificates and keys. …
For SSL key values mismatch issue, it means the private key file does not match the certificate. There are two main reasons. key values mismatch in private key, CSR, and certificate file. certificate chain order is not correct Error message:Cannot load SSL private key file. Error: error: 0B080074:x509 certificate routines:X509_check_private_key:key values mismatch. What is SSL …
An SSL certificate helps to secure the communication between a client (such as a web browser) and a server (such as a website). If the certificate has expired, it can no longer be trusted to secure this communication, and an attacker may be able to intercept and view sensitive information being transmitted between the client …
